Precision CNC Machining China Bronze Bearing Sleeve Custom Copper
Alloy Parts CNC Machining Services Product Description The bronze bearing sleeve is a sliding bearing component
manufactured from high-density copper alloy through precision CNC
machining, utilizing CuSn6.5P0.1 or CuSn8P0.3 bronze as base
material. The product surface features regularly arranged
diamond-shaped oil pockets that quickly form an oil film during
initial operation, reducing friction coefficient. Suitable for
medium-load and low-speed conditions, it offers excellent wear
resistance and long service life, widely applied in various
mechanical sliding parts. Features - High Load Capacity: Static load capacity up to 120N/mm², dynamic load 40N/mm²,
hardness HB 90-120
- Excellent Wear Resistance: Friction coefficient 0.08-0.25, PV value 2.8N/mm²·m/s, extends
equipment service life
- Optimized Lubrication Design: Surface diamond oil pockets store grease, enabling minimal
lubrication suitable for hard-to-lubricate conditions
- Wide Temperature Adaptability: Operating temperature range -100℃~+200℃, meets various
environmental requirements
- Thin-Wall Lightweight Structure: Light weight and compact size helps reduce mechanical structure
dimensions
- Good Thermal Conductivity: Thermal conductivity 60W/(m·K), linear expansion coefficient
15*10⁻⁶/K, ensures stable operation
